Executes a named trigger. Doesnotcache trigger value, so only executes if the sound is already playing. If the intent is for the trigger to execute immediately (if playing) and be called on initialization for all future instances, call 'SetBoolParameter' with the intended initial trigger behavior (true if trigger desired on initialization, false if not).
